Product Introduction

The Euro I Light Truck 4 Ton is a versatile 4-ton-class commercial vehicle engineered for short-distance logistics, particularly excelling in urban-rural cargo distribution. Powered by a Yunnei 4100QB-2 diesel engine, it meets the Euro I emission standard, making it suitable for regions with relaxed environmental regulations or specific operational scenarios like intra-factory transportation.


Available in three vehicle numbers (w2-1, w2-2, w2-3) with a 4×2 drive configuration, this truck offers three cab options—single cab, extra cab, and double cab—to accommodate varying personnel needs. Its key specifications include a gross vehicle weight (GVW) of 6000kg, with curb weights ranging from 3245kg to 3350kg depending on the cab type, ensuring a reliable 4-ton load capacity. The cargo compartment maintains consistent internal dimensions across all variants (4165/3735/3155×1900×1900mm), providing flexible space for standardized goods.


The Yunnei 4100QB-2 engine delivers 83hp (66.2kw) of power and 230Nm of torque, paired with a 5G28 transmission by WLY for efficient power delivery. With a body width of 1880mm, air brake system, and LSPV brake control, it balances maneuverability with safety, making it a practical choice for frequent stop-and-go urban-rural routes.

Key Selling Points

  1. Diverse Cab Configurations
    Offering single, extra, and double cabs, the truck adapts to various operational needs: the single cab prioritizes cargo space, the extra cab balances crew and storage, and the double cab accommodates up to 5 people for small-team operations. This versatility eliminates the need for multiple vehicles to cover different scenarios.
  2. Stable Power Performance
    The Yunnei 4100QB-2 diesel engine, calibrated for 4-ton loads, delivers robust low-speed torque—critical for short-distance transportation with frequent starts and stops. Its 3.612L displacement ensures consistent power output, handling 4-ton cargo efficiently without compromising reliability.
  3. Flexible Load-Bearing Capacity
    With a 6000kg GVW, 2.2T front axle capacity, and 5T rear axle capacity, the truck reliably handles 4-ton loads. Variable curb weights (3350kg to 3245kg) allow users to prioritize either enhanced stability (heavier curb weight) or slightly improved fuel efficiency (lighter variants) based on their needs.
  4. Reliable Braking System
    Equipped with air brakes, front and rear drum brakes, and an LSPV (Load-Sensing Proportioning Valve) control system, it ensures stable braking performance across varying loads and road conditions. This setup is particularly valuable for downhill stretches or sudden stops in congested areas.
  5. Practical Design for Routine Operations
    A 120L fuel tank provides ample range for daily short-distance runs, while 7.00R16 tires and a 5.571 drive axle speed ratio optimize traction on rural roads. The uniform cargo compartment dimensions simplify loading of standardized goods, reducing packaging adjustments.

Differentiated Advantages

Compared to similar 4-ton light trucks, the Euro I Light Truck 4 Ton stands out with unique strengths:


  • Unparalleled Cab Versatility: Few competitors in the segment offer three cab types (single, extra, double). This range allows businesses to align the truck with specific crew and cargo needs—from solo deliveries to team-based operations—enhancing operational flexibility.
  • Engine Calibration for Short-Haul Efficiency: The Yunnei 4100QB-2 engine is tailored for frequent starts and stops, delivering better low-speed torque and fuel economy than generic engines. This makes it ideal for urban-rural routes, where efficiency in short distances is paramount.
  • Standardized Cargo Compartment: Unlike rivals with varying cargo sizes across cab types, its uniform compartment dimensions (4165/3735/3155×1900×1900mm) simplify logistics planning. Businesses can use consistent packaging regardless of the cab variant, reducing operational complexity.
  • Balanced Suspension Design: The leaf spring configuration (3+1/6+7) balances load-bearing strength with ride comfort, cushioning bumps on rough rural roads to protect both goods and vehicle components. This durability lowers maintenance costs over time.
  • Accessible After-Sales Support: Yunnei’s extensive domestic service network ensures easy access to spare parts and maintenance expertise. Common components are readily available in auto parts markets, minimizing downtime for routine repairs.


In summary, the Euro I Light Truck 4 Ton combines cab versatility, tailored engine performance, and practical design to meet the demands of short-distance logistics. Its focus on scenario adaptability and reliability makes it a cost-effective choice for businesses operating in regions with relaxed emission regulations.
